Hair is primarily composed of:

Keratin
Melanin
Sebum
Collagen

The correct answer is: Keratin

Hair is not composed of melanin, which gives skin and eye color but does not make up hair itself. Sebum, an oily substance, is secreted by the scalp to moisturize hair but is not a primary component of hair. Collagen, a protein found in connective tissue, also contributes to healthy hair but is not the main building block. Keratin, on the other hand, is a fibrous protein that makes up the structure of hair and is responsible for its strength and elasticity. Therefore, hair is primarily composed of keratin.
